This law section states that if you are a placer mine operator with a permit from the California Debris Commission, this chapter's rules don't apply to you.

If you run a placer mine, which is a type of mining operation on or near a stream that feeds into the Sacramento or San Joaquin Rivers, you must file a confirmed report with the county recorder where your mine is located. Make sure to do this within 30 days of starting your mining activities.

This section requires that a verified statement must be submitted by either the mining operator or someone authorized to speak for them. This statement needs to include a detailed description of the area to be mined using placer methods. The statement should list the names and addresses of both the landowners and the mine operators, explain the proposed mining technique, and describe how the operator plans to prevent stream pollution from their operations.

If you own or operate a mining property and either change your address, transfer ownership, or change who operates it, you must file a notice with the county recorder's office within 10 days. This notice should state the names and addresses of the new owners or operators.

If you're involved in placer mining near streams that lead to the Sacramento or San Joaquin Rivers, you must follow two specific rules to prevent water pollution: 1) Build a large enough settling pond to clean the used water before it's released into the stream. 2) Use substances like aluminum sulphate and lime, or something similar, to make the solid waste in the water stick together so it doesn't contaminate the water supply for households.

This law allows placer miners using dredging techniques to move their dredgers across a stream without making a settling pond if they believe the cost of doing so is too high. However, they must follow certain steps before crossing. They need to notify local water authorities at least seven days in advance if moving the dredger could affect water clarity. After that week, they have 48 hours to move the dredger, even if it temporarily makes the water cloudy. Once across the stream, they must follow existing rules as detailed in Section 3964(b).

If anyone—a person, a business, or a company—breaks the rules outlined in this chapter, it's considered a misdemeanor, which is a type of crime.

If you operate a placer mine in California without having the necessary permit, it's considered a public nuisance. This can be stopped by a legal action, which either the local district attorney or affected cities or districts can bring, especially if the mining makes local drinking water unsafe. The case will be handled in the county's superior court where the mining is happening, and the court can decide on the appropriate actions to stop the nuisance.

This law ensures that if anyone—whether a government entity or a private party—had the right to start a legal action or get a legal remedy before April 8, 1953, they still have that right today. It doesn't take away any rights or remedies that were available under the laws existing at that time.
